Arduino Pro Websocket - Githubissues

Bug description

@axonasif

A gitpod of a nodeJS websocket see https://github.com/hpssjellis/gitpod-portenta-websocket works using an older Arduino called the Nano33 IOT but doesn't seem to work using the modern "Pro" Arduino Microcontrollers as websocket clients.

signal strength (RSSI):-49 dBm

Starting connection to server...
connected to server failed

disconnecting from server.

The websocket server on Gitpod works as tested by the contained browser page, but the new Arduino PortentaH7 does not connect. The code does work as tested on a different platform. I am not sure if the new Arduino has a security issue causing the problem or Gitpod has the security issue.

Presently I am not sure how Gitpod switches from port 8080 to port 443, which the WiFi SSL client is expecting, but it used to work with the older Arduinos.

If you have any suggestions I can test it out with my Arduino. The Arduino code is in the repository.

Here is the output when it runs (I used a different cloud server): (Kind of messy since it is debug info, but yes it can send a string of 125 characters in a payload 131 bytes long (extra at the start 2 bytes for format codes and 4 bytes for masking)

Any suggestions to try would be appreciated.

Steps to reproduce

Without an Arduino PortentaH7 you wont be able to test the code, buyt everything is in the repository README.md file

Load the gitpod which runs node index.js
make the port 8080 public and view the webpage index.html
connect to the websocket server on the webpage to check that everything runs
run the Arduino code on the portenta using your WiFi credentials and the same URL for the gitpod
The Arduino should receive data from the browser webpage and should every 10 seconds send a 125 character string to the web browser using the socket.

Workspace affected

No response

Expected behavior

See listing above and this image of the webpage
